Welcome to Korea! When you arrive at Incheon International Airport, the two most important things you need right away are a stable internet connection and a transit card.
1. How to get a Korean eSIM
You can easily purchase a Korean eSIM online before you arrive or buy a physical SIM card at the airport booth. Having data makes navigating Seoul much easier!
2. How to get a Tmoney Transit Card
You can buy a Tmoney card at any convenience store (CU, GS25, Seven-Eleven) inside Incheon Airport. You need to top it up with cash (Korean Won) to use the subway and buses.
Terminal 2: GS25 and 7-Eleven are located in the general area, and CU convenience stores are located in the departure duty-free area.
